Lost in the desert

Two guys are lost in the desert, dehydrated, exhausted and close to death. Suddenly one of them smells something.
“Joe, do you smell that, I could swear it’s bacon!”
“Yeah Eric, it definitely smells like bacon!”
With their last bit of energy they crawl over the dune towards the smell. In the distance they see a tree covered in bacon. Joe races towards the tree, but as he gets near it, a machine gun starts to fire, cutting him down.
“Eric, go back!” he yells as he bleeds to death. “That wasn’t a bacon tree, it was a Ham Bush!”
